Plastic
injection molding machine main function is cycling it from melt the
thermoplastic material ,then injection, then pressurize and last cooling ,then
got the products. There are the normal parts assembling: Hydraulic system, injection
system, mold system and clamping system.

·Hopper
from plastic injection molding machine: particle thermoplastic material install
inside the hopper, then feed to the barrel and screw by the weight pressure

·Barrel
from plastic injection molding machine: the barrel loaded the rotating screw
and heated by the heating ring.

·The
rotating screw from plastic injection molding machine: It function is for pressure,
melting and delivery the material, and it formed with feed zone, transition
zone and metering zone.

When
the screw outside diameter is stable, the depth of rotating screw's thread will
be cut down from feed zone to metering zone, and then the material will be melt
by it. The heating ring outside the barrel could keep the material with melting
status. Generally, one set of plastic injection molding machine will have 3
zones or more heating rings for keeping the temperature, the heating rings with
different temperature due to it in different zones.

·Nozzle
from plastic injection molding machine: the nozzle connected with barrel and
main spurge bushing of the mold, and made the apace with sealing.

The
nozzle temperature should be the same with the plastic material melting
temperature or a little lower than it, it could suggest by the material
supplier, because they have more professional ideas.

When
the barrel in a status of full material and will be injection, the head of the
nozzle should be in a correct position. When clean the barrel, should remember
to backward the barrel, should take part of the spurge, then the material will
falling directly.

Hydraulic
system:

Plastic
injection molding machine could supplier a force for open and close the mold, rotating
and drive the screw, push the ejector pin and made the core moving. This step
need the pump, valve and motor, connector and so on parts cooperation.

Control
system:

Control
system could promise the equipments keep working for a long time, could
administrate and control the date like temperature, pressure, injection speed
and the screw speed, position, and the hydraulic system status.

Plastic
injection molding machine function of the clamping unit:

·Support
the mold - Supporting the mold together with the leading it opening and closing,
then it required the clamping system have enough force to moving the movable
platen.

·Clamping
the mold - When the melting plastic material is injection to the mold cavity
should keep the mold with sealing status, so need it to clamping the mold.

Recently
our company is researched new kind of plastic injection molding machine, due to
the market demands.

We
are try our best to supplier customer with high performance, more speed, more
accurate, more stable plastic injection molding machine. DAKUMAR could provide
customer professional suggestions before bought and after bought our machine.

Before
you bought, we could suggest you which kind of machine is the most suitable
based on the mold and products you produced. After you bought our machine, we
can send engineer to installation and training your work. We are the
professional and specialist in the plastic injection molding machine industry!

The
main working principle of plastic molding machine is to use the plastic thermal
physical properties. First, we auto loader the plastic material into the
barrel, which is surround by heating elements melting the plastic. In the
barrel which is assembled with servo motor screw. The plastic melt will flow up
the screw and under the heating condition get tight and move forward to the
screw head. At the same time, due to the plastic reacting force, the screw will
step back. So at the screw head, it formed a plastic melt saving space to
finish its plasticizing process. At the same time, under the injection hydraulic cylinder force,
the screws will injection the plasticizing melt into the plastic mould through
the nozzle. The plastic melt will remain in the mould cavity through the
holding pressure, cooling, process, and then formed into solid shape ejected
out of the mould. So the plastic molding machine main recycle process
including: quantitative feeding-plasticizing-injection-molding the shape-pick
up the piece, then close the mould to the 2nd recycle process.

Normally
to judge a good Plastic Molding Machine performance, first, we will study the
plastic molding machine component brand, then to review the Plastic Molding
Machine performance parameter. Our Dakumar plastic molding machine use famous
brand component to make sure our machine at the high quality level. Below is a
list for your reference.

Dakumar
machinery co. ltd. Zhejiang is a molding
machine supplier in China. Molding
machine supplied by DKM with top class.

DKM
is a molding machine supplier
with our good team:

1. Professional molding machine supplier, also the
molding machine designer, we could design the molding machine based on
different customer requirements.

Some
customer need the servo motor for saving energy, some customer need the
standard machine just for the normal plastic production, and some are need the
short recycle time for injection, then we will design customer with high speed
molding machine. Important, we have our own machine research and development
department, we not only could design the machine for our customer based on
customers' requirements, every time, they try their best to improve the
technical points, and improving the new shape and higher performance of machine
based on the society progress.

2. Enough molding machine spare parts supplier, we have enough stock with
the molding machine spare parts. After customer bought our molding machine, if
you need any parts, which you couldn’t find in your market, then tell us, we
could send for you, and the spear parts from us it could be 100% suitable for
assembling, it is also one of our advantages. There many molding machine supplier in the world,
but as a good molding machine supplier, we think provide customer enough
standard parts is very important.

3. Good after sale
service department, we think a company with good after sale service is also
very important than who have enough experience with machine making. Everything
should be old, so does the machine. When the machine old and have problem,
then, we could help our customer with good after service. Our after sale
service department could help the molding machine owner to adjust the machine
when we delivery the machine as your requirements. Also you could send your
engineer to learn on our company from operating to maintain and adjust.

4. We not just provide customer molding machine, also could supply
customer the whole sets of auxiliary machine, no matter you need autoloader or
water chiller, or other auxiliary machines. The autoloader is for loading plastic
material when injection, could stock and provide material. The water chiller is
used for cooling the mould who with hot runner.

The
auto loader is for stock a parts of plastic material when injection
and it could design with auto and hand work as customer need.

The
water chiller, when we injection the mould, then mould will be with high
temperature, then we should use water chiller to keep the mould with suitable
temperature, then we could get a perfect products.

5. We could provide customer molding machine together robot for
pick up products and help for label. During choice the robot, we could provide
professional idea based on your mould size, label type and production and so
on.

Choice
robot, we could give our customer professional suggestion, and we could design
the robot and mould to make a perfect assemble, we just need customer provide
us mould dimension, injection machine dimension and products dimension, then we
could calculate the best way for your machine and robot.

6. Together supply with molding machine, the most
important from our company is we are also provide customer mold, from children
used to adult used, from industry used to chemical used.

We
provide customers molding machine
together with many equipments as customer needs. Molding machine supplied by Dakumar
machinery co. ltd. with good reputation and you could take it easy for
choice our machine.
